AUTOMATIC LEASH- INDICATOR FOR WARPlNG-FRAMES.

SPECIFICATION forming part of Letters Patent No. 414,243, dated November5, 1889.

Application filed May 29, 1889. Serial No. 312,610. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM A. PATRICK and ALONZO HASTY, citizens ofthe United States, residing at Saco, in the county of York and State ofMaine, have invented a new and useful Improvement in AutomaticLeash-Indicators for \Varping-Frames, of which the following is aspecification, reference being had to the drawings accompanying andforming a part thereof.

The object of our invention is to provide an attachment for use on awarping-frame, which shall automatically indicate the completion of thewinding of a leash, as well as the completion of the winding of anypredetermined number of leashes, both indicators being constructed andarranged so that they shall be readily noted by the operator from infront of the frame, thus avoiding the waste of time and labor attendingthe present method of ascertaining these conditions.

In the drawings accompanying and forming a part of this specification,Figure 1 is a side elevation with a part of the dial-case broken away,showing by the dotted lines the movement of parts at the time of takinga leash. Fig. 2 is a top view or plan. Fig. 3is a front elevation with apart of the dial-case broken away and with the omission of the rearparts.

Similar letters indicate similar parts.

A is a gear having a spirally-grooved hub to, in which hub is astop-slot c.

B is a finger-bar or finger moving in the spiral slot of the hub andpivoted upon and moving laterally on a stud p, projecting from the frameend.

E is an indicator-rod attached to or forming an integral part of thefinger-bar.

F is a lifting-rod attached to and operated by the reed-bar g.

his a dial-case having an opening 0 on its face.

D is a toothed disk or dial.

S is a spring attached to the fingerbar or indicator-rod and the frameend.

m is a mark or stud on the front of the frame I end.

Z indicates the cut-away part of the dialcase.

The gear A and hub a are mounted upon a stud projecting from the frameend. Motion is communicated to the gear from a worm L on the end of ashaft or roll M, over which the threads pass. The worm L meshes with aworm-wheel M on a shaft mounted in the bracket R, and carries a worm N,meshing with the gear A. The tension or friction of the threads in theirpassage through the warper communicates the necessary motion to the rollM. This mode of gearing and driving is common and is not claimed as ourinvention.

The construction and operation of our improved leash-indicator aresubstantially as hereinafter set forth.

The indicator-rod E is secured to or forms an integral partof thefinger-bar B, and is bent at an angle, so that its end shall projectover in front of the warping-frame. On the front of this frame is a studm, which is covered by the end of the rod E when the finger is in thespiral slot of the hub a. This its normal position is retained until bythe motion of the hub the finger traverses the worm and drops into thestop-slot c, when the end of the indicator-rod drops below'the mark m,indicating the completion of a leash and also the cause of the stoppingof the machine. When a stopmotion is used to indicate the breaking of athread, this arrangement of the leash-indicator enables the operator'todetermine at a glance the cause of the stoppage, whether from a brokenthread or the completion of a leash. Attached to the reed-bar by a studor any known device is a lifting-rod F, which has one end bent toproject beneath the indicator-rod, the other end being formed to engagewith the teeth of the dial D. On lifting the reed-bar g preparatory totaking the leash the leashindicator rod is raised by the bent end of thelifting-rod and the finger is Withdrawn from the stop-slot c, and bymeans of the spring S the indicator-rod is drawn inward and the fingerplaced in the spiral slot preparatory to warping another leash.Simultaneously by the same movement of the reed-bar and lifting-rod thedial is moved a single point and indicates the number of leashescompleted. The spring S, attached to the frame and the finger-bar, actsto replace the finger after the completion of a leash and secures theautomatic action of the indicator. I'Ieretofore the operator has beenobliged after taking a leash to walk around the machine and lift thefinger from the stop-slot to the worm-slot, thus consuming much time.

The dial consists of a toothed disk D, in closed in a case h, a part ofwhich is cut away, as shown at Z, to allow the lifting-rod to engagewith the teeth of the disk, as and for the purpose hereinbefore setforth. This dial is usually formed with sixteen (16) teeth, numberedfrom one (1) to sixteen, (16.) An aperture in the front of the caseexposes a single number, the number sixteen (16) being the initialnumber or starting-point. This dial is attached to the front or end ofthe frame by any known means and is easily and quickly adjusted to theinitial point when the desired number of leashes are taken. This dialmay be varied in form and number of teeth to indicate any desired numberof leashes.

Our improvement is not confined to any special style of warping-frame.Although a single style of frame is used in the illustration, it isobvious that by slight changes of form, requiring only ordinarymechanical skill, our improvements may be adapted to a Variety of stylesof warping-frames, to operate as and for the purposesset forth.

We do not claim as our invention either the v gear, slotted hub,finger-bar, or reed-bar as such, they being well-known devices in coninection with a warping-frame.

, purpose specified.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination of the spring S, fingerbar B, and indicator-rodE,With the spirallyslotted hub at, having the stop-slot c,substan'-tially as'and for the purpose specified.

2. The indicator-rod E, lifting-rod F, and stud m, finger-bar B, spring5, reed-bar g, and spirally-slotted hub 01 having stop-slot c, incombination, as and for the purpose specified.

3. The combination of thespirally-slotted hub a, having the stop-slot c,reed-bar g, finger-bar B, indicator rod E, spring 8, liftingrod F, anddial D, substantially as and for the 4. In leash-indicators, thecombination of the dial, lifting-rod, indicator-rod, finger-bar, spring,reed-bar, and slotted hub having a stop-slot, to operate as herein setforth, for the purpose of indicating the completion of a leash and thenumber of leashestaken, substantially as specified.
